In this book Professor Weiss combines thorough research and careful analysis with imaginative solutions and a moral fervour, to show how rules of international law can be applied in an intertemporal dimension, and how the basic principles of the intergenerational equity can be developed to provide new standards for human behaviour. She manages to communicate to the reader not only that the situation is getting desperate but also that human intelligence can in time devise adequate remedies, without destroying completely our way of life.
